Host Plant Chemistry Affects Fungal Interactions, Which Influence the Production of Volatile Fungal Metabolites
DownloadSpring 2019
Mountain pine beetle (MPB) has recently expanded its host range to novel jack pine forests in Alberta. Invasion success of MPB may depend on the outcome of interactions between its primary symbiotic fungus Grosmannia clavigera with other organisms sharing the same host. Among resources-sharing...

Induced monoterpene responses in jack pine: defence against jack pine budworm and a fungal associate of the mountain pine beetle
DownloadFall 2010
My thesis research investigated monoterpene responses in jack pine (Pinus banksiana Lamb.) to different agents to better understand how these responses may influence the spread of the mountain pine beetle (Dendroctonus ponderosae Hopkins; MPB) in the boreal forest. The results support that...

Interactions Between Host Trees, Bacteria, and Fungi: Impacts on Mountain Pine Beetle (Dendroctonus ponderosae) Reproduction
DownloadFall 2012
Warming winter trends due to climate change have allowed for a range expansion of the mountain pine beetle, and the beetle now threatens Canada’s economically and ecologically important jack pine forests. The beetle’s success in jack pine trees will depend upon successful colonization of the...

Intra and inter-plant signalling was investigated in jack pine (Pinus banksiana) seedlings in response to jack pine budworm (Choristoneura pinus, Lepidoptera: Tortricidae) feeding. Defoliation was followed by a fungal inoculation by blue stain fungus (Grosmannia clavigera) to assess resistance....

PLANT FATTY ACIDS INFLUENCE BROOD DEVELOPMENT OF MOUNTAIN PINE BEETLE AND GROWTH OF ITS SYMBIOTIC FUNGUS: IMPLICATIONS TO HOST-RANGE EXPANSION OF AN HERBIVOROUS INSECT
DownloadSpring 2015
Nutritional composition of plants can affect the performance of insect herbivores and their associated microbial symbionts. Mountain pine beetle (Dendroctonus ponderosae) is an important bark beetle species that colonizes many species of Pinus within its historical range and encounter host...
